Case Type   : MOT
Case Name   : 约束相关DDL，创建MOT表，创建约束
Create At   : 2020/10/10
Owner       : opentestcase001
Description :
    1.设置enable_incremental_checkpoint参数为off,并重启数据库
    2.创建普通MOT行存表，创建约束，清理环境，删除内存表
    3.恢复环境默认配置，修改enable_incremental_checkpoint为on，并重启数据库
Expect      :
    1.设置成功，重启数据库成功
    2.创建内存表成功，创建约束成功，清理环境成功
    3.修改参数成功，重启数据库成功
